D.1 Features

The XVR-50 graphics accelerator is a 24-bit on-board PCI-based graphics frame buffer. The XVR-50 graphics accelerator offers the following features:

2D 24-bit color graphics

Flexible 8-bit and 24-bit color application support

HD15 monitor connector for a wide range of Sun monitors

3D support through Sun OpenGL for Solaris software

D.2 Video Formats

TABLE D-1 lists the monitor video formats supported by the XVR-50 graphics accelerator.

To get a list of available screen resolutions for your display device, type:

host% fbconfig -res \?

If you have selected a resolution where support for this resolution cannot be verified, fbconfig displays the following output:

SUNWpfb_config: Cannot verify that selected resolution is a supported video resolution for this monitor

TABLE D-1 lists video formats supported by the HD15 port.

TABLE D-1 XVR-50 Graphics Accelerator HD15 Video Formats
Display Resolution	Vertical Refresh Rate	Sync Standard	Aspect Ratio Format
1600 x 1200	60 Hz	VESA	4:3
1600 x 1000	66, 76 Hz	Sun	16:10
1440 x 900	60 Hz	VESA	16:10
1440 x 900	76 Hz	Sun	16:10
1280 x 1024	60, 75, 85 Hz	VESA	5:4
1280 x 1024	67, 76 Hz	Sun	5:4
1280 x 800	76 Hz	Sun	16:10
1152 x 900	66, 76 Hz	Sun	5:4
1152 x 864	75 Hz	VESA	4:3
1024 x 768	60, 70, 75, 85 Hz	VESA	4:3
800 x 600	56, 60, 72, 75 Hz	VESA	4:3
720 x 400	85 Hz	VESA	9:5
640 x 480	60, 72, 75 Hz	VESA	4:3

Note - The XVR-50 graphics accelerator video composite sync is an XOR composite sync.

Note - Not all resolutions are supported by all monitors. Using resolutions that are not supported by the monitor may damage the monitor. Please refer to your monitor manuals for supported resolutions.

The default resolution is dictated either by EDID information from the connected monitor or by the console resolution that is set (see TABLE D-1). When no monitor is connected to supply EDID information, the default resolution is 1024 x 768 @ 75 Hz.

D.3 Sun OpenGL for Solaris Software

The Sun OpenGL 1.5 for Solaris software supports the XVR-50 graphics accelerator through software implementation.

D.4 Man Pages

The XVR-50 graphics accelerator man pages describe how you can query and set frame buffer attributes such as screen resolutions and visual configurations.

Use the fbconfig(1M) man page for configuring all Sun graphics accelerators.
SUNWpfb_config(1M) contains XVR-50 device-specific configuration information. To get a list of all graphics devices on your system, type:

host% fbconfig -list

This example shows a list of graphics devices displayed:

  Device-Filename              Specific Config Program
  ---------------              -----------------------
  /dev/fbs/pfb0                SUNWpfb_config

Type the fbconfig -help option to display the attributes and parameters information of the man page.

host% fbconfig -dev pfb0 -help

To access the fbconfig man page, type:

host% man fbconfig

To access the XVR-50 graphics accelerator man page, type:

host% man SUNWpfb_config

D.5 Optional Video Output

The default system uses a resolution suggested by the monitor as long as the monitor is connected to power and connected to the XVR-50 video port. This is the default the system uses if no fbconfig commands have been given, or after entering fbconfig -dev pfb0 -defaults.

To manually set up a video output resolution, do the following:

1. Set the desired screen resolution. For example, type:

host% fbconfig -dev pfb0 -res 1280x1024x60

2. Log out, then log in.

To find all possible XVR-50 graphics accelerator resolutions, type:

host% fbconfig -dev pfb0 -res \?

D.6 Default Color Depth

1. Set or reset the default color depth.

To set 8 or 24 as the default color depth, type /usr/sbin/svccfg.

/usr/sbin/svccfg -s x11-server setprop options/default_depth=8
/usr/sbin/svccfg -s x11-server setprop options/default_depth=24

The default color depth is 24.

2. Log out and then log back in for the change to take effect.

D.7 Checking Device Configuration

Type fbconfig to check the X window system (-propt) and XVR-50 graphics accelerator (-prconf) device configuration values.

The fbconfig -propt option displays the values of all options (for the specified device) saved in the OWconfig file (see below for an example). These are the values the X window system will use the next time it starts on that device:

host% fbconfig -dev pfb0 -propt
 
-- Graphics Configuration for /dev/fbs/pfb0 ---
 
OWconfig: machine
Video Mode: not set
 
Screen Information:
        Fake8 Rendering: Disable
        Gamma Correction: Disable

fbconfig -prconf option displays the current XVR-50 graphics accelerator device configuration (see below for an example). If certain values differ from those displayed in -propt, it is because those values have been configured since the X window system started.

host% fbconfig -dev pfb0 -prconf
